servo: Merge #3748 - Improve logical geometry formatting (from mrobinson:trimmer-flow-tree-output); r=mbrubeck

Browse Source 
Logical geometry is complicated, so the string formatted output is
verbose. This means that flow tree dumps often go well beyond the
edge of the terminal screen. With a simple notation, we can shorten the
output and make it slightly easier to read. This notation also makes it
more similar to the formatted output of Rect, Point2D, and Size2D.
